Please visit these class websites! You'll find that many are extra­ordinary. These are all entirely individual student efforts, so please write to their authors, help them learn, and help them to help make a difference.

One way to comment -- or ask questions is to use the excellent markup application a.nnotate. Fred Howell of Textensor Limited has graciously provided us with a subscrip­tion to allow us to experi­ment with uploading pdfs and other types of documents to share for group annotation and collab­oration on pdfs.
